Keytruda Sensitive TIL and Tumor co-culture



Tumor infiltrating lymphocytes (TILs) are immune cells that have migrated into the tumor environment in order to attach cancer cells. TILs are comprised of immune sub-populations that  play various roles in the immune-tumor interactions.  TILs are removed from a patient’s tumor and are then treated in the laboratory with substances that activate the lymphocytes to help them better kill the patient’s cancer cells (source: NCI).

Using our Keytruda sensitive TIL and Tumor cell line, this assay attempts to screen drug candidates in comparison with Keytruda (anti-PD1) therapy.

What is the assay setup?

  1. Co-culture tumor and TIL for 24 hours in the presence of drug candidate
  2. After 24 hours harvest the supernatants
  3. Measure cytokine release and tumor lysis

What are the study arms?

  1. TIL + Tumor+ Keytruda (anti-PD1)
  2. TIL + Tumor+ <drug candidate (per dose)>
  3. TIL + Tumor
  4. TIL + Tumor + DMSO
  5. TIL
  6. Tumor

How many doses are included?

The assay is run in a 96 well plate and can accommodate up to 40 doses of the drug candidate. Each dose is a well.

What is included the price?

  • Multiplex cytokine readouts – IL-2, IL-6, IL-4, IL-5, IL-9 IL-10, IL-13,IL-17, TNF-α, IFN-γ
  • Assay setup and methods used
  • Raw data files for cytokines
